Application filed lovember 3,1921. seim in. name.

My invention relates to trucks.

It has for its object to provide an im'' proved variable gage truck. A further ob-' ject of my invention is to provide an 1111-;

6 proved and simplified means whereb trucks of any desired gage may be manu actured at reduced expense and whereb the gage of an given truck may be varie readlly and qulckly in the field, this at the same time that an exceedingly rugged and strong construction is PI'OVldGd. These and other advantages of my improved construction will, however, 'hereinafter more fully appear.

In the accompanying drawings I have shown for pur oses of illustration one embodiment' whic my invention may assume in practice.

In these drawings, Fig. 1 is a side elevation partially 1n section of the truck equipped with this form of my invention.

Fig. 2 is a bottom plan new of such a truck.

Fig. 3 is a sectional view on hne 3 -3 of Fig. 1, the wheels also being shown ad usted in position for a diiferent gage in dotted lines as in a modified construction.

Fig. 4 is a detail longitudinal sectional view showing the wheel connections.

In this i1 u shown a'truck body 1 which may beof any desired type, herein of the type adapted to carry a mine compressor mechanismand, of substantially rectangular form having depending strengthening ribs 2 around its edges and longitudinal and transverse depending strengthening ribs 3, 3', the truck wheels 4 being disposed beneath the truck body 1 and connected thereto in an improved manner hereinafter described.

In my improved construction, on the bottom of the body 1 a plurality of pairs of transversely disposed angle irons 5 is provided, the angle irons each bein dlsposed so that one of its surfaces rests Tat upon the bottommost surface of the body 1, and the angle irons herein being attached to the ribs 2 by suitable connecting means hereln in the form of'screws or bolts 6. As shown the flan es of each pair of angle irons are also pre erably turned adjacent one another and extend downward to form a pair of transverse slides herein disposed at opposite ends of the truck body. Mounted in each of these slides is a plurality of wheel carrying umts 7 "herein in the form of flanges of the angle. irons 5 strative construction, I have interchangeable what mayv be called, wheel yokes having a central longitudinally disposed open ace 8 in which the wheels 4 rotate on stub a as secured 111 *depending brackets 9 carried on the SldSpf the yokes. As shown these okes are also provided with dependin gui es 10 receivable between the de en mg flan es on the angle lIOllS 5 and sli able longitu 1y of the angle irons into an desired osition between the adjacent mem rs 2 an 3, and these guides are attached to the depending b suitable means, herein in the form of ,a plurality of bolts 11 which may be received in an of a plurality of perforations 12 cut in t e dependmg flanges of the members 5. Attention is also directed to the fact that the members 7 are also provided with flanges 13 on their upper surfaces and between the guides 10, while means carried by the truck body, herein the transverse strengthening ribs 3, are flanged and grooved as at 14 to cooperate with the surfaces13 and thereby further stiffen the construction, the greater .9 bulk of the strain bein taken on these surfaces so that the principal duty of the connections to the angle irons is to prevent lateral displacement of the members 7.

As a result of my improved construction, it will be noted that it is possible for the wheel carrying members 7 to 'beadjusted into any desired position between the adjacent members 2 and 3 of the frame, the members 7.being freely slidable relative to the angle irons 5 and the members 3. It will further be noted that by simply attaching the bolts 11, these members 7 may be rigidly connected to the truck body in any position and that whenever it is desired to 5 alter the gage as for instance-in the field, it is only necessary to remove the bolts 11 and adjust the member 7 into the desired position. It should also be noted that as shown in Fig. 3 the members 7 ma also be adjusted slightly beyond the latera limit of the truck body if desired, if the length of the angle irons 5 is suitably increased. Attention is also directed to the fact that my improved construction enables a variable 1 gage truck to be produced which is not onl of an exceedingly rugged character and we adapted to the adjustments desired'by the manufacturer and user, but which may also be manufactured at small expense.

' cally described one form w claims.

While I have in this application specifii'ch my invention may assume in practice, it will be understood that this form of the same is shown for purposes of. illustration and that the.inventionmay be modified and embodied in various other forms without departing from its spirit or. the scope of the appended What I claim as new. and desire to, secure by Letters Patent is:

1. In a truck, a truck body, longitudinally spaced guiding means beneath the bottom thereof, wheel carrying members adjustably mounted on said guiding means for adjustment in directions axially of the wheels relative thereto, and means whereby said members are allowed to be removed by movement directly away from said guiding means. 7

2. In a. truck a truck body, a plurality of pairs of laterally disposed members beneath the bottom thereof, wheel carrying members mounted between each pair thereof for adjustment transversely of said truck body, and removable means for holding said members in osition, said means being necessarily removed during adjustment.

3. In a truck, a truck body, a plurality of pairs of laterally disposed members beneath the bottom thereof, wheel carrying yoke members transversely adjustably mounted between the elements of each pair thereof, and means whereby said yoke members are movable in only one direction at a time while normally positioned between said lateral members. 7

4. In a truck, a truck body, a pair of laterally disposed members carried on the bot- 7 tom thereof, wheel carrying members operatively mounted between said members and adjustable transversely of said body, and coo crating engaging surfaces carried on said gv teel carrying members and said truck 5. In a truck, a truck bod a plurality of pairs of laterally dispose members carried on the bottom thereof, wheel carrying yoke members adjustably mounted between the elements of each pair thereof for move ment laterally of said body, and cooperating engaging surfaces formed on said wheel carrying members and said truck body.

6. In a truck, a truck body, a plurality of members attached to the bottom thereof and having parallel depending portions presenting a guideway, wheel carrying members disposed between said depending portions and aving portions slidable thereover, and removable means for connecting said portions, said means being necessarily removed during said sliding action.

7. In a truck, a truck body, a plurality of members attached to the bottom thereof and having parallel depending portions presenting a guideway, wheel carrying members disaving portions on their opposite ends slidable thereover and portions intermediate their ends engageable with the bottom of said .body,.and means for connecting said wheel carrying members to the de ending portions. 8. In a truck, a truck b0 y, longitudinally spaced guidin means between the ends t ereof, and w eel carr ing members fixed as to having a longitu inal component of movement relative to said body by said means and adjustable laterally threbetween.

9. The combination with a truck body having laterally adjustable wheel supports therefor and ,detachable guiding means therefor, of means for allowing said sup- I ports to be moved to any required position relative to said guiding means including means necessarily removable from said device during adjustment, said latter means being adapted to substantially rigidly hold said wheel supports when in adjusted (pit;-

sition and to positively prevent'lateral placement thereof.

10. The combination with a truck body having laterally adjustable wheel supports,

of means for holding the same in substantially rigid position including a nut and bolt connection, and means independent of said.

connection for preventing longitudinal displacement of said supports after being positioned in any required adjusted position.

11. The combination with a truck body having wheel supports and means for engaging the latter, of means for permitting adjustment of said wheels axially while preventing displacement of said supports-laterally of the wheel axes, and means for holding the same in rigid position with respect to said body, said last mentioned means including only a bolt and nut connection cooperating with said engaging means and supports.

12. The combination with a truck body having wheel supports therefor, of means for rigidly holding the same in position including relatively removable cooperating members, and means independent of cooper-' .having portions. cooperating with said flanges, and means for securing said support to-said guides.

15. In a truck, a truck body having trans verse flanges thereon, s aced guiding means secured to said body, w eel supports adjustably mounted between said gulding means and having flanges cooperating with said flanges to prevent longitudinal displacement thereof, and means for securing said supports to said guiding means.

16. In a truck, a truck body having 11' depending transverse flange thereon, transversely disposed members secured to said body, a laterally adjustable unitary wheel support, and means cooperating with said members for clamping said support in rigid relation against said an e.

.17. In a truck, a truck od'y having transversely grooved depending flanges, transversely extending angle members secured to the bottom of said body, unitary wheel supports disposed between said angle members and having projections thereon cooperating with'the grooves in'said flanges, and means for securing said supports to said angle members in difl'erent laterally ad'usted positions. In testimony whereof I a x my signature.
